' vULcANIz'ING APPARATUS.

Specification of Letters Patent. Patented Dec. 21, 1920.

Application led November 19,1919. Serial No. 339,036.

To all whom t may concern:

Be it known that I, NICHoLA Yosiir Mo- MrrsA, a Macedonian, residing at Granite City, county of Madison, and State of Illinois, have invented a certain new and useful Improvement in Vulcanizing Apparatus, of which the following is a specification, reference being had to the accompanying drawing, forming a part thereof.

This invention relates generally to vulcanizing apparatus and,` more particularly, to a certain new and useful improvement in apparatus designedv and adapted especially for use in connection with the vulcanization of the inner tubes and outer casings of pneumatic tires, the principal object of my present invention being to provide an efficient device or apparatus especially designed for the purpose statedk which is readily separable to permit with convenience and facility the mounting thereupon, and the dismounting or removal therefrom, of a tube, casing, or the like.

lith the above and other objects in view, my present invention resides in the novel features of form, construction, arrangement, and combination of parts hereinafter described and afterward pointed out inthe claims. y

In the accompanying drawing,

Figure 1 is a plan view, partly broken awa-y, of a device or apparatus embodying my invention;

Figs. 2 and 3 are transverse sectional views thereof on approximately the lines 2-2 and 3 3, respectively, Fig. 1;

Figs. 4, 5, land 6 are detail views in section; and

Fig. 7 is a perspective view of the tool or Spanner by which the tube or casing-engaging members of the device or apparatus are locked to retain the tube or casing and-unlocked to permit removal of the same.

Referring now more in detail to the said drawing, in which like reference characters refer to like parts throughout the several views, 1 indicates the base-member, which is preferably in the form of a iiangedv ring, this member 1, which may be pressed, cast, or otherwise suitably constructed, being the element on which the tube, casing, or the like'to be vulcanized is first arranged or mounted. I have omitted showing the soapstone and the details of the core and tube devices, as they are generally well known.

At what might be designated its outer peripheral margin, the body of ring 1 is formed or provided with an annular series `of spaced upstanding inwardly-presented hook-members or projections 3; and at its so-called inner peripheral margin, the ring 1 is forined'or provided with a substantially similar vseries of spaced hookmembers or projections 8, the hooks 8, however, heilig outwardly or oppositely disposed, and preferably staggered, relatively to the hooks 3.

similarly so-called 'outer peripheral margin,

the body ofvring 2 is cut away or apertured, as at' 2", to accommodate the hook-members 3 of ring 1, the hooks 3 and 8 of ring 1, engaging or interlocking as described with ring 2, serving to perform the function, in addition to the function hereinafter appear ing, ofiirmly or rigidly'holding the rings 1 and 2 from relative rotatory movement.

Disposed ilatwise for rotatory movement uponthe body of ring 2 and intermediate the oppositel series of hooks 3 and 8, is a locking-member or ring 4 preferably provided within its area with arcual slots 5. Upstanding from ring 2 and having their shanks disposed in the slots 5, are T-headed bolts or the like 6 for holding the ring 4 operatively in position upon the ring 2. For purposes shortly appearing, it will be noted particularly in Fig. 1 that the ring 4 is formed or provided at its inner and outer peripheries with series of recesses or cut-outs 4d and 4b, respectively, which re cesses or cut-outs are spaced equidistantly with the series of hooks 3 and 8. It may be here statedthat the ring 4, when in normal or ring-unlocking position, l occupies such positiony upon and relatively to the ring 2 that its cutouts 4a and 4b register, respectively, with the apertures or cut-outs 2b and 2c of the ring 2.

Disposed upon, and'xed at an end to,

the upper face of the ring 2, and having preferably the form or shape seen particularly in Fig. 6, are springs 9--9a; and for coperation with said springs, respectively, the ring 4 is suitably formed or provided with openings or slots 11-11a. The springs 9-9"l and their coperating slots 11-11x=` are so relatively located that, y when the ring 4 is in its said normal position, one of said springs, as, for instance, spring 9, is adapted to yieldingly engage at its free end with an end-wall of its coperating slot 11 to releasably retain the ring 4 in said normal position, the other spring 9a being then compressed or depressed between the rings 2 and 4, and that, when the ring 4 is in abnormal or ringlocking position, the spring 9EL is similarly adapted to releasably engage at its free end with an end-wall of its coperating slot 112l to likewise releasabl'y retain the ring 4 in said abnormal or locking position, the spring 9 being then correspondingly compressed or depressed between the rings 2 and 4. For conveniently accommodating the interposition of the springs 9 and 9a between the rings 2 and 4, the locking -ring 4 is preferably grooved or cut-away on its undersurface, as at 13.

vIntermediate the openings or slots 11 11, the ringy 4 is provided, as seen in Fig. 1, with an additional opening or slot 14, the openings or slots 11-11n-14 being adapted to receive the bent-or flanged ends of a suitable spanner-wrench or other tool 12, shown in Fig. 7, whereby the ring 4 may be conveniently rotatorily actuated to and from ring-locking position.

In use or operation, the tire, tube, casing. orl other article t0 be vulcanized together with the core upon which. the same is usually formed is rst arranged or mounted upon the base-member or ring 1, after which the upper or top ring 2 is placed in article-engaging position as described upon ring 1, the'ring 4 being in described normal position and the hook-members 3 and S of ring l being freely accommodated by the openings or cut-outs 2 land 2b of ring 2 and the registering cut-outs 4h and 4L of ring 4. By means of the Wrench. or other tool 12, then applied upon the ring 4, the spring 9 is depressed Out of engagement with its coperating slot 11 and ring 4 rotarily moved on ring 2, its cut-outs 4a and 4b being moved out of registration with the then protruding hooks 8 and 3 and ring 4 rigidly engaged and locked atv its peripheral inner and outer margins with the hooks 8 and VThe ring 4 is so-actua'ted until opposite spring 9, engages as described with 'its coperating ,slot 11a, when the Wrench or other tool is removed. The ring 4 is then, as will be evident, releasably locked in abnormal position' and' rings 1 and2firm1y and securely locked together in assembled or article-engaging relation. The casing or tube is then, as is usual, packed in soap-stone or the like, and is then suitably moved into the vulcanizing oven, my new apparatus serving to rigidly and firmly supportingly hold the article to be vulcanized in position during the vulcanizing operation, which usually is carried out in an oven especially designed for that purpose. After vulcanization, the locking-ring 4 is similarly, but reversely to normal position, actuated by means of the wrench or tool 12, when, as will be evident, the top ring 2 may be readily separated and disassembled from base-ring 1, and the vulcanized article then, with convenience and facility, removed from the device.

In arranging or mounting the casing, tube, or other article to be vulcanized upon the base-ring l, such ring is usually placed flatwise upon a table or other support, as will be understood; to maintain `the device relativelyT fixed or rigid during, and thereby facilitate, such operation, the ring 1 is provided upon its under side with an annular series of sockets or recessed members 15 adapted t0 seat upon and removably engage with holding-posts 16 upstanding from the table or support, as seen particularly in Fig. 3.,

It will be noted in Fig. 1 that a passage 10 is formed by and between the members or rings 1 and 2, through which a steam or vapor pipe may be conveniently passed to the vulcanizing core or chamber.

I am aware that changes in the form, construction, arrangement, and combination of the several parts 0f my device or apparatus may be made and substituted for those herein shown and described without departing from the nature and principle of my invention. l
